From what I've played of Call of Juarez: The Cartel it appears to be just as bad as everyone worried it would. The game is packed with tiny glitches, odd AI behavior and questionable graphics. But it also has a couple of levels starring President Barack Obama.
OK, not really. What it really has is a DEA agent who likes to wear a Barack Obama rubber mask in the early missions while robbing and killing drug dealers, ala Point Break.
I plan to finish playing through the game, mostly because it's so very very bad, but I'd highly recommend you avoid the game. I'll let you know if, by some miracle, the game comes around in the bottom half or something.
I'm also still trying to figure out why all of the cars driving around in L.A. have Texas license plates.
